.1,5 `WILLLAM. S. ooPER, of Philadelphia, county of Philadelphia and State of Pennsylvania, have ini vented an Improved Faucet andStop-Valve, of which the following is a specification. l Nature and bjectof the Invention.

My invention relates `to improvements' in faucets having vertical valvecasings, from which project inlet i and outletbrancheg and consists- First, of a stationary gniding-plataadapted tothe interiorof the valve-casing,` as hereafter describedand havinga square openingforthe passage-of the square.

-portion of the valve, which is thus prevented from gturning.

Second, of a spiral spring, arranged within the casfing infthe manner described hereafter, soas to server y the twofold purpose of maintaining the plate for guiding the valve in its proper position, and maintaining the unt which operates the valve in tight contact with itspackiug. i Y.

\ Third of a mode, described hereafter, of preventing theuid in the valve-casingjfrom gaining access .to

y and injuring" the leather packing against which the nut foroperating thevalve has to bear; Y Fourth, of a mode, described hereafter, of insuring a thorough `and contnuoustlubrioation of the nut'and screw for Operatngthe valve by the water or other fluid which gains access to the interior of the valve.- `casing. f i i Description of f ttcccompeng/ing `Dru/Mang.

i t GewaZ'Descrtpaqn. y

The body of the faucet Aconsists of three hollow l branche'sA A and B, the inlet branch A being separated from the outlet branchA and from the branch B, which constitutesi the valve-casing by a partition4 a, in whichv is a circular opening, b; l

The valve which, when depressed, bears upon this partition, consists ofthe hollow circular portion @fitted withsnitable packingsthe` intermediate square por- 1 tion d, and the screwfstem e, `z tdapted to a nut, j, forin-` ing a pai-tof the stem It, which iitsfsnugly, but so. as to turnfeely in, and projects through a cover, z', the

pla-u of part of the faucet latter being screwed or otherwise secured to the top of the valve-casing. B, and the said stem h being furnishediwith alsuitable h'audle,` i'.

The squareV portion d of the valve is arranged to t and slide in a square opening of the plate j, which it's snugly-in a recess in the valve-casing, and which rhas a' notch, k, to preventit from being turned round in the said recess. i

Between this gniding-plateand an external collar,-

m, on the nut f, intervenes av spiralrspringil, which 1 serves the twofold purpose of depressing the plate and thereby maintaining itin its proper position in the casing, and of elevating thenut and maintaining it in tight contact with the packing in the under side'of the cover i.

`Repeated tests have proved that leather. forms the best` packing material for the bearing-surface of such parts' of vfaucets as have to be repeatedly turned; Vhence the packing nr' in the recess in the under side 'of the cover, consists of a leather ring for receiving the pressure of the angc .m of the nut f. It is importaut,' however,'that the leather should be protected as far as pnossible from the action of the Iwater in' the valvecase'. f

It will ,be observed that this end is accomplished by making the packing 'recess just large enough to receive the collar/m., and making the packing so thin that when thevcollar is .in its place, it will have penetrated a short distance into the said recess, thereby excluding the waterfrom the packing. aThis will be distinctly observed on reference to' the enlarged View, fig. 7, where itwill also be seen that the upper rface ofthe collar is provided with a projecting ling, which, compressing the packing, causes 'the latter to embrace the stem h.

It will be seen,.on referring to fig. 1, that the thread ofthe nutf does not extend to the upper end of the Y same, but that a threadless recess is there formed,v this recess communicating, through perforations p,

with the interior ofthe casing B, so that the wateror other uid in the latter may gain free-access tothe interior of the nut, and serve as a constant lubricant for the screw.

The shape and the relative Yposition of the two i branches A and A of the faucet are somewhat peculiar, the inlet branch, A, being tubular at the outer end, but being contractedjvertically, sro as to assume a transverse section of anoval form as the branch apV preaches the `tubular casing, (see fig. 4L) The object of this is to make the branch as nearly aspossible of the'same sectional area throughout, so that on closi-ng the valve there may be no excess oi'water at any one.-

ipoint inthe branch to freeze and burst `the same.

'lo make the valve of a tubular form 'ofthe-same vinternal area throughout, would involve the necessityv Claims.

1. The detachable platej, arranged'within thecase so as not to turn within the latter,-and so as to guide the valve and prevent it from turning, substantially as described.

2. The spiml spring D, in combination with the guide-plate j, es described, and serving the twofold purpose of maintaining the said plate in its place and the collar against the packing, asset forth.

3. Tlleannularrb on the collar m of the revolving valve-spindle, in combination with the-recess and. its packing-n, in the cover 'Las specified.

In testimony whereof I have signed my name to thisspecication in the presence of twol subscribing witnesses.
